Question

我正在尝试使用从存储库安装的boost 1.42在Ubuntu 11.10下编译一个C ++程序（我也试过自己构建boost，但结果与repo-boost相同）。源文件编译但链接器出错...我试了好几个小时但找不到解决方案，也许有人可以帮助我...

这是Makefile中的目标

CXX = /usr/bin/g++

LDFLAGS = -L.  \
          -Lpath/to/libMy_Lib.a

CFLAGS = -I.   \
         -Wall \
         -g    \
         -O0

OBJECTS = obj1.o obj2.o

%.o: %.cpp
    $(CXX) -c $*.cpp -o $@ \
         -Wno-deprecated   \
          $(CFLAGS)

all: program

program: $(OBJECTS)
    $(CXX) $^            \
    $(LDFLAGS)           \
    -o myProg            \
    -lboost_regex        \
    -lboost_filesystem   \
    -lboost_date_time    \
    -lboost_system       \
    -lboost_thread       \
    -lMy_Lib

libMy_Lib.a是一个也使用boost的库（我在同一系统上编译时没有问题）。所有的库在/ usr / lib中都可以正常...

这是输出ld生成（我使用make 2＆gt;输出）http://ubuntuone.com/6QlU7AUZGgLGIu7sHbvDHm

也许库的顺序不正确（我知道boost_filesystem依赖于boost_system，但我不确定其余的）或者我忘了指定一些我的程序需要链接到的其他库...

这真的让我感到烦恼，我觉得我不敢看到它......

这些错误消息令人印象深刻：

我在'undefined reference'之前添加了一个换行符......

我认为你应该在任何Boost库之前列出你的库，它使用Boost函数。
